The California-based optoelectronics manufacturer Exar has announced the production of a four-channel, I2C0-controlled LED driver.
The XRP7620 is specially designed for colour mixing applications where a combination of four LEDs is used to generate either white light or a range of colours from the spectrum.
Four independently adjustable current sinks provide precise control of each channel allowing an exact setting of each LED's brightness, interfacing with processor-based designs to provide unprecedented ease of use through a standard I2C bus.
Eric Pittana, director of marketing for Exar's power management product line, said the technology is designed to meet the demands for visual indicators and improved display readability in handheld devices.
He commented: "The XRP7620 enables designers to achieve true white light for improved screen resolution or any colour of light by means of simple software settings. The XRP7620 represents true creativity and customisation at your finger tips."
The news follows the release by ON Semiconductor of new linear constant current regulators for LED applications.
